Why doesnt the color not show on my character model?
I confirm there is no material defined for your model.

Here is the way to create it and assign the texture:




Go to the material tab
Create a new material
Change the color, indicating you want an image texture
Choose the image
Then you can use ShiftZ to toggle the 3D view to rendering mode (you can also use material or texture modes).


The created material can also be defined using the Cycles nodes system (both UI does the same, but nodes is more clear if your material becomes complex):




Create the material
Open a node view
Choose material nodes: by default a simple diffuse setting is created
Add ShiftA an image texture node
Connect it to the diffuse color
Select the wanted image
